About Walnut Ave
Over ¼-acre premium lot created through an SB-9 subdivision. Allows one or two detached homes or a duplex, plus one ADU, for up to three total units, with flexibility for phased development. Approval is ministerial only—objective standards apply with no discretionary review, no CEQA, and no public hearing. Under SB-450, the city must approve or deny a complete application within 60 days. Setbacks include a 20’ front setback per city standards and reduced 4’ side and rear setbacks per SB-9. Previous plans for a 2,134 SF two-story home are included. Ideal for a custom home or income-producing project. Seller is a licensed general contractor with expertise in combining manufactured home and custom-built elements to reduce overall costs, and is open to build-to-suit or joint venture opportunities.
